ADHD test for adults: the WHO ASRS screener, explained by a psychiatrist

This is the Adult ADHD Self-Report Scale (ASRS v1.1), Part A: the six-question screener developed with the World Health Organization. It takes about two minutes, needs no sign-up, and your answers never leave your device.

Below the test you will find what most online ADHD quizzes leave out: how the score is calculated, what a positive or negative result really means, and what to do next. A two-minute questionnaire cannot diagnose ADHD, but it can tell you whether a proper assessment is worth your time.

ADHD test — ASRS v1.1, Part A

Answer based on how you have felt and behaved over the past 6 months.

1. How often do you have trouble wrapping up the final details of a project, once the challenging parts have been done?

2. How often do you have difficulty getting things in order when you have to do a task that requires organization?

3. How often do you have problems remembering appointments or obligations?

4. When you have a task that requires a lot of thought, how often do you avoid or delay getting started?

5. How often do you fidget or squirm with your hands or feet when you have to sit down for a long time?

6. How often do you feel overly active and compelled to do things, like you were driven by a motor?

This is a screening tool and does not replace a diagnosis by a psychiatrist. Your answers are not stored or sent anywhere. ASRS v1.1 questions © World Health Organization.

What this ADHD test measures

The ASRS was developed by the World Health Organization with researchers at Harvard as part of the World Mental Health Survey. The full version has 18 questions mapped to the ADHD criteria. Part A, which you just answered, contains the six questions that best separated adults with ADHD from adults without it.

The first three questions are about executive function: finishing tasks, organising, remembering obligations. The last three are about procrastination and inner restlessness, which is how hyperactivity usually looks once a child with ADHD becomes an adult.

How the score is calculated

The threshold is not the same for every question:

  • Questions 1–3 count if you answered Sometimes or more often.
  • Questions 4–6 count only if you answered Often or Very often.

Four or more answers above these thresholds mean your symptoms are highly consistent with adult ADHD and further assessment is warranted. The thresholds differ because the questions differ in how well they discriminate: forgetting appointments even sometimes is more telling than fidgeting sometimes, which almost everyone does.

What a positive or negative result means

In the original validation study the six-question version reached a specificity of 99.5% and a sensitivity of 68.7%, with 97.9% overall classification accuracy. In practice:

  • A positive result is rarely a false alarm. It is worth taking seriously.
  • A negative result does not rule ADHD out. Roughly three in ten adults with ADHD score below the threshold, more often women and people with mainly inattentive symptoms.

The test is not a diagnosis. Diagnosing ADHD needs a clinical interview based on DSM-5 criteria, evidence that symptoms were present in childhood, impairment in more than one area of life, and ruling out other explanations. No questionnaire does that.

What else can look like ADHD

Several conditions produce almost the same picture, which is why a positive screen is the start of an assessment, not the end:

  • Chronic short or broken sleep, the most common trap
  • Anxiety and depression, which both impair concentration and working memory
  • Thyroid problems, iron deficiency or low vitamin B12
  • Burnout and long-term work stress
  • Alcohol, cannabis or other substances

The main way to tell them apart is timing: ADHD is present from childhood and stays fairly stable over the years, while depression and burnout have a beginning and come in episodes.

What happens next

The next step is not another test but a clinical assessment by a doctor: a structured interview, a childhood history (often with the DIVA-5 interview), and screening for other conditions. With me, an adult ADHD assessment takes on average two 45-minute sessions (€130 each), online in English or Greek, or in person in Trikala, Greece. It is individual, so occasionally more sessions are needed, and you are always told in advance. It ends with a written report.

If you live outside Greece, read ADHD assessment and treatment in Greece, in English, including what is and is not possible with prescriptions across borders.

Frequently asked questions

Is this ADHD test free?

Yes. There is no sign-up, email or payment. Your score is calculated in your browser and your answers are not sent or stored anywhere.

How accurate is the ASRS screener?

In the original validation study the six-question ASRS had a specificity of 99.5% and a sensitivity of 68.7%. A positive result is rarely a false alarm, but a negative result does not rule ADHD out: roughly three in ten adults with ADHD score below the threshold.

Does a positive result mean I have ADHD?

No. The ASRS is a screening tool, not a diagnosis. Diagnosing ADHD requires a clinical interview, evidence that symptoms were present in childhood, impairment in more than one area of life, and ruling out other causes such as anxiety, depression or sleep problems.

Can I use this test for my child?

No. The ASRS was developed and validated for adults aged 18 and over. Children and adolescents are assessed with different tools.

Can I show the result to my doctor?

Yes, as a starting point for the conversation. After the test you can print or save a summary of your answers as a PDF. No health system accepts a self-report questionnaire as a diagnosis.

Is there a Greek version?

Yes. The same screener is available in Greek, with the same scoring, on the Greek ADHD test page.
